Microsoft just released a giant "Patch Tuesday" bulletin for the month. Weird thing about this update? More than half of the bugs found in Microsoft products were reported by none other than Google engineers.

It's not unusual for Googlers to uncover security flaws in Word, Office, Internet Explorer, and so forth. Mountain View's finest found one in October, November, and December, and none in January. And Microsoft gives credit where credit is due. But this time around Google guys discovered 33 out of 57 issues. Mateusz "j00ru" Jurczyk sniffed out 32 of them, five of which Gynvael Coldwind collaborated on. And it was one of the biggest updates ever, closing in on the standing record of 64.

So just why are Google employees looking around Microsoft software? Bugs are probably found because engineers are researching other products, like Google Chrome's PDF viewer. These guys also just might be genuinely interested in finding flaws. But Microsoft would probably like to see some of its own employees addressing the problems. [Microsoft via The Verge]
